Dealing with heating loss

If you’re experiencing a loss of heating, follow our system checklist to help you identify the problem. Not so bad in summer, a nightmare in the winter. 

If you’re keen to take on the task yourself, here are a few things you can try to get the system up and running.

Check the system

  1. Is the electric power supply to your boiler switched on? There is normally an electrical isolation switch for your heating system, (normally near to either the boiler or the time clock) make sure the switch is in the ‘on’ position.

  2. Is the gas supply to your property turned on? Check that the Emergency Control Valve (ECV), this is located by the gas meter, hasn’t been knocked to the off position. There should be a label on the ECV indicating which way to turn the valve to the ‘on’ position.

  3. Is your boiler switched on? Make sure normal operational lights are illuminated and any displays have the normal display present.

  4. If your boiler has a pilot light ensure it is still present. If not, re-light it in accordance with the manufacturer’s instructions.

  5. If your boiler doesn’t have a pilot light, is there a warning light advising you to ‘reset’ the appliance?

  6. Does your boiler have any warning lights indicating low water pressure? This can be rectified by following the instructions’ provided by the manufacturer.

  7. Is your programmer on? Check to see if the display is present and showing the correct time, ensure that the time is set to the ‘on’ position.

  8. Is your room thermostat set high enough? Ensure that your thermostat is set high enough, normally set around 21°C.
